1.1 This practice covers the method of classifying, identifying, and characterizing the failure modes in adhesively bonded fiber-reinforced-plastic (FRP) joints. The FRP used in developing this practice consists of glass fibers in a thermoset-polyester-resin matrix, commonly referred to as sheet-molding compound, or SMC.

1.2 One objective of this practice is to present comprehensive definitions of possible failure modes to serve as a guide for contracts, drawings, product specifications, and product performance.

Note 1:  Figures 2 through 11 referred to in the practice are contained in the ASTM adjunct, Color Photographs of Failure Modes. 2

Fig. 4—Cohesive Failure

Fig. 5—Thin-Layer Cohesive Failure

Fig. 6—Fiber-Tear Failure

Fig. 7—Light-Fiber-Tear Failure

Fig. 8—Stock-Break Failure

Fig. 9—Mixed Failure—40 % Fiber-Tear Failure, 60 % Light-Fiber-Tear Fiber

Fig. 10—Mixed Failure—32 % Adhesive Failure, 68 % Fiber-Tear Failure

Fig. 11—Mixed Failure—20 % Adhesive Failure, 60 % Light-Fiber-Tear Failure, 20 % Fiber-Tear Failure

Note 2:  This practice may be used to describe the failure modes generated from testing, using procedures such as Test Methods D3163, D3164, D3165, D3807, D5041, D5868, and SAE J1525.

1.3 The values stated in SI units are to be regarded as the standard.

1.4  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
